I have an EB w/ seasonal skin issues (not food related) and her regimine: holistic diet, Missing Link supplment, Lipiderm supplement, Biotin supplement, plan yogurt added to the mix with either a Claritin or Benedryl for good measure on days when she's eating herself alive. She gets bathed 1x-2x weekly depending on the severity. She used to get irritations similar to what you pictured as well as spotty hair loss. I read on another board (can't remember which - sorry) that Nu-Stock is like a miracle product, so I ordered a container of it (you can Google search for online merchants) and it's worked wonders. Not only has it eased her itchiness enough where she'll barely itch/scratch/gnaw at herself for a about 2 days post-application (reapplication is every three days, I believe) but the hair regrowth rate was incredible - I was stunned that the online claims were actually true. I got it for about $12-15 and it was worth every penny. It IS messy going on and does dry to a funky yellow color, but once you brush off the excess you can't even see it on their skin and it won't get all over your carpeting. Granted, this may not work for others, but maybe it's worth a shot ...
